基于临床数据挖掘技术的腹腔镜结直肠癌手术评估体系的构建及应用

目的 整合优势科研资源,搭建良好的科研平台,开展单（多）中心临床试验,以中国人的临床数据科学地评价腹腔镜结直肠癌手术目前仍存在争议的问题.方法 以南方医院2008年10月自主开发的一款专门以腹腔镜结直肠癌手术为数据架构,同时适合于回顾性和前瞻性临床研究,既能科学管理和深度分析临床数据,又能满足多单位合作需要的数据挖掘系统软件为数据平台,构建腹腔镜结直肠癌手术评估体系,开展单（多）中心腹腔镜结直肠癌手术研究.结果 历时1年多的开发和完善,南方医院已经使用该软件系统按照标准回顾性录入1200余例临床资料,构建了单中心腹腔镜结直肠癌手术评估体系.同时该软件系统作为＂中国南方腹腔镜结直肠外科研究组（SCLCSG）＂的数据平台,已在第1期临床研究项目＂腹腔镜与开腹结直肠癌手术的回顾性多中心对比研究＂中成功运行,迄今已录入8200余例病例数据.以南方医院数据完成＂腹腔镜与同期开腹直肠癌根治术后肿瘤学结果对比研究（单中心）＂,结果显示,腹腔镜直肠癌根治术的远期复发和生存并不劣于开腹手术,甚至优于开腹手术的肿瘤学结果.结论 该手术评估体系和临床数据挖掘软件设计达到预定目标,在腹腔镜结直肠癌手术领域具有广泛的应用前景和网络化升级扩展的潜能,值得推广.

Construction and application of evaluation system of laparoscopic colorectal surgery based on clinical data mining

Objective To construct a clinical database for laparoscopic colorectal surgery in Chinese population using computerized technique. Methods A clinical database system was constructed and used in multi-/single-center studies on laparoscopic colorectal surgery. Results The data of more than 1200 cases in the Nanfang Hospital during the past year were collected retrospectively. The database was used as the platform for "Southern China Laparoscopic Colorectal Surgery Study Group (SCLCSG)" and was used in the first stage of the clinical research of "Multicenter retrospective study of laparoscopic and open procedure for colorectal cancer" among 11 hospitals in Southern China. In order to test the system, the database was also used in "comparative study on oncologic results of laparoscopic versus open radical resection for rectal carcinoma". Conclusions The evaluation system is reliable and efficient. This system has established a clinical database for laparoscopic colorectal cancer surgery and can be widely applied for the clinical research for colorectal cancer.
